Leaf wagon

ABSTRACT

A leaf carrying cart having a pair of rectangular frames supporting a pair of baskets hinged at the top to permit the forward basket to rotate between a first position where the two baskets are extended and a second position with one basket folded on top of the other. One of the baskets is provided with an opening for the discharge of contents of the cart and a rotating cover to either open or close the opening.

This application is a continuation-in-part of my application Ser. No.07/297,216 filed on Jan. 17, 1989.

The present invention relates to hand carts and more particularly tohand carts especially useful for the gathering and removal of leaves.

At the present time the wheelbarrow appears to be most generally usedcart for the collection and carting away of leaves. When such a deviceis utilized the leaves must be lifted into the cart which ordinarilylacks sufficient capacity to carry many leaves at one time. Awheelbarrow with sufficient capacity to carry a lot of leaves at onetime tends to be very large and heavy. In addition, the wheelbarrow isnot suited for riding over rough terrain.

Another problem is the manufacture, assembly and shipping of hand carts.Even the wheelbarrow when disassembled for delivery and assembly by theconsumer for use, is quite often a bulky device.

A variety of hand carts are shown in U.S. Pat. Nos. 1,955,997,3,774,930, 4,240,353, 4,375,113 and 4,735,424. None of the precedingpatents teaches or suggests the present invention.

It is not difficult to design hand carts, sleds and other carryingdevices to satisfy many different requirements. However, in a moderneconomy the cost of storage of merchandise as well as the cost of laborof assembling the components is prohibitely expensive so that it is nolonger economical to assemble, package and store hand carts in stores orwarehouses. Instead, considerations of economy require bulky items, suchas hand carts to be constructed in a way that allows them to be packagedand stored in compact boxes and to be assembled with a minimum use oftools.

SUMMARY OF THE PRESENT INVENTION

In the present invention there is provided a hand cart uniquely usefulfor the collection and carting away of leaves.

A preferred embodiment of this invention has the capacity to carry muchlarger volumes of leaves normally found in wheelbarrows or other devicesof similar type. In addition, it can be tipped at an angle sufficientlyshallow so that the leaves can be raked onto its carrying platformrather than being lifted. Furthermore, the wheel construction permitsconvenient movement over rough terrain and the use of conventionalbicycle wheels of thin axle construction so that the cart incorporatingthe principles of this invention is relatively light in weight. Afurther feature of this invention is that in its knock down form priorto assembly in the form it is shipped it requires far less space and islighter in weight than any similar devices available.

In another embodiment of this invention, the cart can be folded forconvenient storage and has provision for removal and bagging of theleaves without anymore than minimal handling of the cart itself.

It is thus a principal object of this invention to provide an improvedhand cart for use in collecting and carting away leaves.

This and other objects of this invention will become better understoodin the light of the accompanying detailed description of a preferredembodiment of this invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring now to FIG. 1, cart 10 is composed of a frame 11 made of framemembers 12 and 14 supporting a bed 16, a pair of wheels 18 and 22, and ahandle 24.

For details of frame members 12 and 14 with bed 16, reference is made toFIG. 2. Members 12 and 14 are identical with each other except that oneof the members, in this case member 14, is provided with a supportingplate 26 whose purpose will be explained below.

Member 14 is U-shaped in construction with an internal U-shaped groove28 and a pair of grooves 32 and 34 along the top surfaces of theparallel arms of member 14.

Member 12 is similarly provided with an internal groove 36 and parallelgrooves 38 and 42.

Bed 16 is a flat sheet of plywood in a standard stock size, namely, fourfeet by eight feet, and members 12 and 14 are sized and constructed toaccommodate bed 16 in the manner now to be described.

As seen from FIG. 2, bed 16 is slid into member 12 riding in groove 36and then member 14 is engaged with bed 16 until members 14 and 16 cometogether with their legs abutting each other as seen in FIG. 2a. Plate26 is seen to overlap the underside of both members where they cometogether and may be screwed into attachment as shown by openings 26a toaccommodate screws (not shown).

Once members 12 and 14 are assembled with bed 16 in place, wheels 18 and22 are mounted.

Wheel 18 is supported by a wheel support bracket 44 whose details areseen in FIG. 3. It should be noted that wheel 22 is similarly supportedon the other side of cart 10 shown in FIG. 1 except that its wheelmounting frame is not visible.

Bracket 44 is a made of a hollow elongated box 46 of wire or similartruss-like construction supporting a pair of inverted V-shaped slots 48and 52 to accommodate the axles 54 and 56 seen in FIG. 3a of wheel 18.This wheel support is conventional for bicycles but unique in thisparticular application. It is thus simple and quick to mount and demountthe wheels of cart 10.

Bracket 44 is provided with a pair of mounting plates 58 and 62 so thatframe 44 can be attached to one side of cart 10 as illustrated inFIG. 1. Plates 58 and 62 are provided with screw holes 58a and 62a,respectively, for this purpose.

Handle 24 is made of piping or round wire and is provided with arms 64and 66 with braces 64a and 66a to slide into brackets 68 and 72 (as seenin phantom in FIG. 2) on one side of member 14. Handle 24 may be maderemovable if desired to be moved to the other side of cart 10, for whichadditional brackets on member 12 would be provided. Also, handle 24 maybe made of pieces which can be assembled. It will also be noted thathandle 24 is U-shaped with L-shaped bottoms to form arms 64 and 66 atabout right angles to the upright arms so that the leaves can be loadedonto or off loaded from cart 10 from either end as will be describedbelow with handle 24 not interfering with the movement of the leaves.

One of the features of this invention is that the leaves can be loadedon cart 10 by raking rather than lifting. As seen in FIG. 4, the lengthL of frame 11 is sufficiently large in relation to the size or diameterof wheels 18 and 22 that when one end is lowered to collect leaves, theangle a made by frame 11 with respect to the ground is sufficientlysmall so that substantially all leaves raked aboard will remain and notslide off.

Another feature of this invention is that wheels 18 and 22 may bestandard bicycle wheels, sufficiently large to ride over bumps,obstacles, and ruts with minimal effort on the part of the user of cart10.

Still another feature of the invention is the use of the side wheelsupporting brackets as described which in effect form trusses to supportvery short shafts. This makes it possible to employ relatively thin andlightweight wheels with thin, short axles so as to keep the weight ofcart 10 down to convenient and manageable proportions while at the sametime being able to handle very large amounts of leaves at any one time.

In order to facilitate the unloading of the leaves in cart 10 into aplastic bag, as seen in FIG. 5, a plastic funnel shaped snout 74 havinga wide mouth 76 which goes over the end of cart 10, and a smallersection 78 over which the opening into plastic bag 82 is placed. Theleaves are merely raked into bag 82 for disposal.

As pointed out earlier, the size of the frames 12 and 14 when connectedtogether could be made to accommodate a standard plywood type base ofthe size which is 4 by 8 feet. With this arrangement, a merchant couldstore cart 10 in comparatively small packages, as seen in FIG. 6,without the base 16 and the seller would have the advantage of beingable to sell the cart at a lower cost because the base 16 would have tobe purchased separately or the consumer may already have one availableat home.

In another embodiment of this invention, shown in FIGS. 7, 8 and 9,there is shown a cart 110 made of two parts, 112 and 114, with hinges116 to be folded in the manner indicated by arrow A, and having a handle117.

Part 112 consists of a bed 118 and a pair of side walls 122 and 124hinged to fold inwardly as seen in FIG. 8. Hinges 126 are shown for sidewall 122 in FIG. 7. Part 114 is of similar construction.

For supporting wheels 128 and 132 there are provided a pair of frames134 and 136, similar to frame 44 in the embodiment of FIGS. 1-6,attached to part 114 so that part 112 can be pivoted as shown in FIG. 9.A member 138 joining frame 134 and 136 provides a support for part 112when in the fully open position shown in FIG. 7.

In the embodiment of FIGS. 7-9, cart 110 may be all wood or metal inconstruction. When folded up as shown in FIG. 9, handle 117 and wheels128 and 132 may be removed for shipment and/or storage. In any event,once folded, it is a compact unit which can be deployed for use quicklyand conveniently.

For example, in the arrangement of FIGS. 7-9 just described, the sidewalls fold down and the bed is hinged for folding over. If desired, theside walls may be fixed, and the adjacent corners of the side wallsabove where the bed folds may be provided with hinges.

In addition, the two parts of the bed may be made to telescope ratherthan fold.

Under some circumstances, it is helpful to have a leaf wagon withgreater capacity and capable of being folded up readily for storage,requiring less assembly when it is to be used.

Such an embodiment is illustrated in FIGS. 10-15. Leaf wagon 200consists of a rectangular rear frame 202 supporting a pair of wheels 204and 206 in frame 208 for the former, the frame for wheel 206 not beingvisible. Wheel 204 in frame 208 and wheel 206 in the hidden frame areidentical in construction to wheel support bracket 44 and wheel 18 shownin FIGS. 1 and 3.

Resting in and supported by frame 202 is a bathtub shaped basket 212 cutoff at 215 as illustrated. Basket 212 has a rear wall 216. A pair ofarms 218 and 222 extend from frame 202 and support a handle bar 224.

Wheel frame 208 extends forward of basket 212 as more clearly shown inFIGS. 14 and 15 in order to provide better balancing of leaf wagon 200when in the extended position shown in FIGS. 10 and 12. The frame forwheel 206 is directly opposite frame 208 and extends forward of basket212 in a similar manner.

As seen in FIG. 11, the bottom of basket 212 adjacent rear wall 216 hasan opening 226 with a cover 228 pivoted about a pin 232 and a handle 234to move cover 228. By rotating handle 234 counter clockwise, opening 226is exposed to permit emptying of the contents of wagon 10 into a bag 236shown in FIG. 13; by rotating handle 234 clockwise, opening 226 would beclosed off. Around the bottom of opening 226 may be provided a lip 238to support bag 236.

On the outside of rear wall 216 may be provided an extensible member 242to act as a third leg when extended to support wagon or cart 10 as seenin FIGS. 14 and 15. A lock member 243 may be employed to lock member 242in place.

The front of wagon or cart 200 is provided with a V-shaped basket 244supported on a rectangular frame 246, the cross section of basket 244representing a continuation of the cross section of basket 212, asillustrated. Basket 244 and basket 212 are connected through a pair ofhinges 248 and 252 so that basket 244 may be pivoted clockwise as seenin FIGS. 14 and 15 to permit more convenient storage of wagon or cart200 when not in use.

As seen in FIG. 10a, hinge 248 which is identical to hinge 252 consistsof a shaft 255 inside of a sleeve 254 to which wing or extension 258 isattached and would rotate. Wing 256 is attached to a sleeve (not shown)located beyond sleeve 254 also to rotate about shaft 255. Extensions 256and 258 may be bolted on as shown.

In the open position, shown in FIGS,. 10, 12 and 13, frames 246 and 202come together to prevent member 244 from dropping below the positionshown in FIG. 12.

It will be seen that the embodiment illustrated in FIGS. 10-15 is aconvenient wagon or cart capable of carrying a substantial load, is easyto unload, and convenient to store.
